-
Originally in (5.11.8) was unnecessarily restricted to lie in the interval . In fact,
may lie anywhere in the complex plane.
Suggested 2015-02-28 by Nico Temme
- Addition (effective with 1.0.10):
-
To increase the region of validity of this equation, the logarithm of the
gamma function that appears on its left-hand side has been changed to
, where is the general logarithm.
Originally was used, where
is the principal branch of the logarithm.
